Another sprocket question
 

Does anyone know if this chain & sprocket combo ----> http://clevelandspeedshop.com/collec...and-cyclewerks

will work on this bike ----> http://www.motobuys.com/lancer-enduro-250.html

Everything I read about the 200 & 250cc Dual Sports says they are not geared well for the street. I am going to have to re-sprocket mine
for maximum street ability. My understanding that D.I.D. sprockets & chains are of high quality.

If not, would someone who has been down this road before be so kind as to point mi in the right direction as to what would be the best sprocket to get. Need to maintain long runs on 60 MPH. ( 30 min. drive, twice a day, at 60 MPH )

THANKS!!!!!!!

I can't answer your question about fitment but I just went through a sprocket change myself. I changed my front sprocket only and the difference is simply remarkable night and day. If I were you I would purchase the largest front sprocket that will fit your bike and start there. Or at least 2-3 teeth sizes bigger. They are so inexpensive I bought 3 different sizes and ended up using the largest one.

I say start with the front sprocket because its a simple 5 minute or less change out.

Judging from the photos of that bike it looks like it has more street oriented gearing so you may not have to make any changes. The JTR279 rear sprocket configuration is what fit's all 3 of the Chinese bikes I've owned. http://www.jtsprockets.com/catalogue/sprocket/JTR279
That's for a 520 chain but JT sprockets also makes them for a 428 chain.
The Honda CG clone engines I have all use the JTF1264 front sprocket for 428 chain.

Thank you both!!!! :-D

I will try the front sprocket thing first. Hopefully will have enough slack adjustment that I will not have to use a new chain. But if I do, I just do.

Years ago, (8 to 10 years or so), the rear wheel hub pattern of the majority of Chinese enduros was based on the 1980 XL185. I had ordered a 44 tooth sprocket from Dennis Kirk for my Jetmoto 200 using the above bike for ordering. I believe these come with 50 tooth rear sprockets. But, in order not to have to play with the chain, it would be best to try a front sprocket. Adjuster, which sizes did you order? I am fairly confident a 17 will fit, which is the stock one on my TMEC, but perhaps an 18 might fit?

I now have 13 14 16 17 tooth front sprockets. I am using the 17 and I am sure it is the largest that will fit. No more room for the chain/sprocket combined width without using a dremel to remove some metal.

I found on my lifan that a 17T front with a 42-46T rear worked well on the road.

I followed Kato's guidance, and my bike is a good all-around DS now.

Thanks Kato. I ordered a 17T sprocket to go on the bike when it gets here for initial assembly. It is good to know there seems to be a general
" Do this " on sprocket tooth count for all the 200cc Dual Sport/Enduro
Just going by the majority of You Tube vids and the great knowledge
of the many fine folks on this forum that has been there, done that. :)
So 17T/46T seems to be the best combo for mostly on road use.

46T rear will still allow you to venture offroad and handle hills better on road. I found that going lower than that made me slip the clutch more to get moving and that I really didn't gain any top speed with a 42T. 45/46 seems to work well. Really depends on what you can get. 17T front. If you want to go trail riding you can get a 15-16 tooth to lower it and just swap.

I run a 15 front and 36 rear. my bike will pull to 8200 rpm in top at about 78mph, it's a 200 CG engine with a 30mm mikuni and a couple of other simple mods

You have a bit of weight advantage with yours. 15/36 equals 2.4/1 ratio. 17/46 equals about 2.7/1 and 17/42 equals about 2.45/1 ratio. The 2.7 seems to work well for the dual sports offroad.

2.7/1 (17/46) is the stock ratio on the Lifan gy5 and it's about perfect for street or gravel roads. It's too high for off road so I carry a 15 tooth front sprocket that can be put on in a few minutes without changing the length of the chain.
The specs on the bike in question list the rear wheel as 17" so the circumference may be a bit smaller than the 18" wheel used on the Lifan GY5 and others.

My lifan came stock with a rear 56T dinner plate. It would climb mountains, but useless on the street.
